In recent years, we have seen sales people from numerous OEM equipment manufacturers make the claim that use of any battery but the OEMs will result in the OEM voiding the warranty on the equipment. Not only is this illegal under both US and European law, but in many instances is directly in opposition to the OEM's own policy. For instance, Motorola Symbol Technologies specifically addressed this issue in their Product Marketing Bulletin #1114 where they explicitly state:
“It is critical that you understand that a customer's warranty is not automatically voided simply because that customer purchased a third-party battery. We may not say or imply that. Also, you may not state that a third-party product will damage the unit, impair performance or cause safety concerns unless you have been advised by Symbol Legal that there is testing to validate the claim.
False claims regarding the quality, safety or performance of a competitive product can expose the Company to liability.”
